AbstractThe focus of this paper is a case study of a woman in the first trimester of pregnancy who presented with metastatic breast cancer. The bony spread of the metastases was rapid and it was necessary to treat the patient as soon as possible after the period of organogenesis (days 18-60 of human gestation). This stage is the phase of greatest sensitivity of teratogens and the malformations are observed most often. Yet, the choice of third-line chemotherapy was difficult because of anthracycline-resistant metastatic breast cancer. The world literature reported cytotoxic combinated regimens as the standard of care for the management of the metastases. The development of new antitumoral strategies with less toxicity and their encouraging results led us to the approval of docetaxel for the treatment of the patient even though it had never been tested in pregnancy. Docetaxel is a potent inhibitor of microtubule depolymerization and has a unique ability to alter certain classes of microtubules. The monochemotherapy was administered once every 3 weeks for a total of three cycles until 30 weeks of gestation. During the 32nd week of pregnancy the patient delivered a female infant whose birthweight and Apgar score were normal. The infant did not have any anomalies. The woman finished her treatment in puerperium and she received three cycles of docetaxel. The patient has been receiving vinorelbine (one cycle every 2 weeks) for 2 years; her last follow-up was good and showed that the progression of the metastases had stopped. The daughter's psychophysical development was normal.
